SUMMARY:
This Solution applies to SonicMQ Version 4 on Windows platforms.
It discusses why an ActiveX client might not return errors when attempting to connect to a SonicMQ 4 Broker which isn't running.
EXPLANATION:
Below is an extract of the Chat example (provided by SonicMQ) attempting to connect to the SonicMQ Broker. The complete example can be found in the "%SONICMQ%\samples\ActiveX\Chat" directory.
------------------- Begin example --------------
...
Dim connectresult As String
connectresult = ProgressJMS.jms_CreateQueueConnection(username, password)
If (connectresult < 0) Then
TConnectStatus.Text = "NO"
failmsg = "jms_CreateQueueConnection_withDefaultUser failed"
GoTo ErrorHandler
Else: TConnectStatus.Text = "OK"
End If
...
--------------- End of the example ------------
When using JRE 1.3.0 and earlier, it appears that even if the SonicMQ Broker is not running, the variable "connectresult" above will always return 0 (zero). This means that ErrorHandler within the condition block will never be reached.
SOLUTION:
Install JRE 1.3.1_02 or later to solve the problem.
Replacing the version of JRE when using SonicMQ ActiveX can be done via the following steps:
1) Uninstall the SonicMQ ActiveX Client using Control Panel >
Add/Remove Programs
2) Uninstall the current version of JRE that you wish to remove using
Control Panel > Add/Remove Programs
3) Install the new version of JRE
4) Reboot the machine
5) Install the SonicMQ ActiveX Client
